Changing your air filter is a simple yet important maintenance task that helps keep your HVAC (heating, ventilation, and air conditioning) system running efficiently. Here’s a step-by-step guide on how to change your air filter:
New air filter (make sure to purchase the correct size and type for your HVAC system)
Screwdriver or tool (if necessary, depending on your HVAC system)
Turn Off the HVAC System:
Before you begin, turn off your HVAC system to ensure safety during the filter replacement.
Locate the Air Filter:
Find the location of the air filter. In most homes, the air filter is located near the return air duct or furnace. Common locations include inside the furnace cabinet, in a wall or ceiling grille, or in a dedicated filter slot.
Determine the Filter Type and Size:
Check the existing air filter to determine its type (fiberglass, pleated, HEPA, etc.) and size. You can find this information printed on the filter’s frame.
Purchase a New Filter:
Purchase a new air filter that matches the type and size of the old one. It’s essential to use the correct filter to maintain the efficiency of your HVAC system.
Open the Filter Compartment:
If the filter is located inside the furnace cabinet, open the access door. In some cases, you may need to use a screwdriver or other tools to remove screws or latches securing the door.
Remove the Old Filter:
Carefully slide out the old air filter. Note the direction of the airflow arrow on the filter; this indicates the correct orientation for installing the new filter.
Dispose of the Old Filter:
Properly dispose of the old air filter. Some filters can be recycled, while others may need to be discarded in the trash. Check local regulations for disposal guidelines.
Install the New Filter:
Insert the new air filter into the filter compartment, making sure to align it with the direction of the airflow arrow. Ensure the filter fits securely in the slot or frame.
Close the Filter Compartment:
If you had to open a door or panel to access the filter, close and secure it. Make sure it is properly sealed to prevent air leakage.
Turn On the HVAC System:
After replacing the filter, turn the HVAC system back on. Check for proper airflow and listen for any unusual noises that could indicate a problem.
Set a Reminder for Future Replacements:
Note the date of the filter replacement and set a reminder to check and replace the filter regularly. Most filters should be replaced every 1 to 3 months, but this can vary depending on factors such as filter type and household conditions.
Regularly changing your air filter helps maintain good indoor air quality, prolongs the life of your HVAC system, and ensures it operates efficiently.
